To all whom it may concern l j Be it kno'wn' that I, JUs'rUs R. KI'NNEY, a citiz'len of the; United States of America, and a resident of Dorchester, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Starting Devices for Motor-Cars,

. of which the following is a specification.

a piston chamber and normally closing the passage to another chamber in which is positioned a radial blade secured to said supplemental shaft, said piston chamber being provided with means for admitting thereto compressed air or other fluid to move said piston with its shaft endwise so that said shaft will engage the engine shaft and in so doing uncover the passage between said chambers andadmit the compressed air or other fluid to the other chamber against saidr'adial blade'and cause an oscillation of said shaft, thereby imparting to the engine shaft an initial rotation.

The invention consists further in mechanism for reciprocating and oscillatingsaid actuating shaft by means of fluid pressure under the control of the chauffeur, and for returning said shaft to its normal position by means of fluid pressure after an initial rotation has been imparted to the engine shaft; 1

v The invention further consists in certain novel features of construction and arrangement of parts which will be readily understood by reference to the description of the drawings and to the claims hereinafter s m The invention asherein shown and described contains many features shown and described in another application of mine H p 1.

Similar characters designate like parts of the same, the cutting planebeing on line throughout the several figures of the draW-' ing's. In the drawings, 10 represents a cupshaped memberprovided with a cylindrical Y chamber 11, said cup-shaped member 10 being secured to a rear plate 13 by means of a plurality of bolts 14 passing through a" flange 15 formed upon said cup-shaped member. The rear plate 13 is secured in a' fixed position-in any well-known manner, as, for instance, by means of screws engaging the threaded openings 16 in the lugs 17 formed 11,011 said rear plate 13. An actuating sha -t 18, mounted in suitable bearings formed in the said cup-shaped member 10 and said rear plate 13,. is positioned Within the centerof said chamber 11. The outer end of said actuating shaft 18 is squared as indicated at 19 to receive a crank whereby the shaft 18 may be actuated in the usual manner when desired. The opposite end of said shaft 18 has secured thereto a clutch member 20 and in alinement with said-shaft 18 is an engine shaft 21 havingsecured to its end a coacting clutch member 22.- These.

clutch members 20- and 22 are normally sep'- arated by means of a spring actingupon one face of a piston 24 secured to or formed upon the shaft18 and mounted in a cylindrical chamber 25 formed in the back plate.

13, said piston chamber being preferably of less-diameter than thecha mber "l1. 1 s

:by the actionfihereo oi} thespring 23, is

limited by the hub of the clutch member contacting witlnthe closing cap26 of the chamber so that a compartment 27 is always left between the forward face of the piston 24v and the inner end of the piston chamber 25. Communicating with the compartment 27 is a passage 28. formed in the ,back plate 13, from the outer end of which cfcxtends a supply pipe 29 communicating with the compressed air tank 30. At a suitable point in the line of ipe 29 so that 1t 1s readily accessible to the c auffeur is a. threeway valve 31, which is of any Well-known construction, and is normally closed. Extending from the compartment 27 is another passage 32 smaller than the passage 28, thls passage 32 communicating through an open mg 33 with the chamber 11.

Within the chamber 11 and keyed to the shaft 18 in such a manner as to permit a reciprocatin movement of said shaft,'is a piston mem r 34, the opposite faces of which bear respectively against .the inner faces of .the cup-shaped member 10 and the rear plate 13. Secured to or*formed upon the lston member 34 is a segmental blade 35 tlie outer wall of which contacts with the cylindrical inner wall of the chamber 11. Secured to the on shaped member by means ofbolts 36 and by means of. a bolt 37 extending through both said cupshaped mem her 10 and the rear plate 13, is a .segmental abutment 38, the inner wall of which contacts with the peripher of the piston memher 34. The uncovere radial walls of the Zabutment 38 are provided with buffers 39 and 40'of rubber or any other suitable resilient material. The buffer 39 extends sufficiently beyond the face of the abutment 38 ,to prevent the opening 33 being closed at any time when the blade 35 is in its normal 'piston chamber 27 until the position, as; indicated in Fig. 2 of the drawmgs. A branch pipe 41 leads from the supply pipe 29 to the chamber 11 on theoppo site side of the abutment 38 from the opening 33. In this line ofpipe 41 is a valve 42 normally closed toprevent the passage of the compressed air from the tank 30 into the chamber 11. 1 This valve 42 like the valve 31 -a three-way valve, and both of these valves in their normal position are'open to the atmosphere. The piston 24 has secured thereto a packing member 43 which norfluid tinder pressure, while both valves 31 and 42 are in positions to prevent the passage of the compressed air from the supply tank 30 through the pipes 29 and 41 into the interior of the startlng device. When it is desired to impart a rotary movement to the engine shaft 21 to start the engine, the

chauffeur opens the valve 31, permitting the air or other fluid contained within the tank 30 to pass throughthe pipe 29 into the comnartment 27, the passage 32 being closed by the packing 43 upon or secured to the face of the piston 24. The admission of the compressed air into the' chamber 27 acting against the face of the piston 24' causes said piston and the shaft 18 on which it is mounted to be moved toward the engine shaft 21 sufficiently to permit the clutch' passage 28 into the chamber 27 will then flow through the passage 32 and the opening 33 into the chamber 11 between the abutment 38 and the radial blade 35. The action of the compressed air upon said blade will cause it to be moved'i'nthe direction of the arrow at on Fig. 2until it buffer 40, which buffer ment in that direction.

strikes the yielding will limit its move- This movement of the blade 35, secured as it is to the piston member 34, keyed to the shaft 18, will cause an oscillation of this shaft, and, through the clutch members 20 and 22, impart an initial rotation to the engine shaft. As soon as the engine has been started in this manner, the valve 31 .is then moved into. the position shown in Fig. 4 of the drawings, thereby preventing the further admission of compressed air to the chamber 27, but permitting any compressed air which remains therein to passtherefrom through the passage 28 and pipe 29 to the outlet 44 in the valve casing. The valve 42 is then moved into'the position indicated-in Fig. 4 of the drawings, thereby permitting the compressed air from the tank 30 to pass through the pipe 41 into the chamber 11 in the rear of the blade 35, said compressed air acting on said blade to return it to its normal posihon, asindicated in F 1g. 1 of the drawings,

any air in advance of the blade while the shaft 18 is reversely rotated bein 'permittcd to pass outwardly from the c amber 11 through the opening 33, passage 32, into the chamber 27, and then therefrom thr ough the passage 28 and pipe 29, as heretofore'described. The sprin 23 will return thevpiston 24' to its normal osition and the startingdevice will then e in qondition to re- "It is believed that the operationand many, advantages of the invention will be thoroughly understood from the foregoing.
